You had known then what you know now about the environment / climate change?
I had my DC before the last couple of years when reports from the UN etc have come out about unsurvivable conditions, the end of civilisation etc within maybe 30 years, us having 12 years to do anything about it. And seeing the subsequent reactions from governments worldwide which can be summarised as giving zero fucks.
Knowing what I know now, despite how my children are my life and I couldn't love them more, I doubt whether I'd have had children (they're still young). I feel so scared about what they will face in their lifetime and guilty about bringing them into it.
